Description

Technical Field

[0001] The invention relates to a foldable multi-purpose textile shoe cover, which is highly fitted, easy to put on and take off, simple and comfortable, beautiful and practical, and belongs to the field of shoe covers. Background Art

[0002] With the continuous progress of social development, people's requirements for daily necessities are getting higher and higher. There are many places and environments in life that need to use shoe covers. Hospitals, laboratories, dust-free workshops, cultural relics protection sites, cultivation bases, pharmaceutical companies, food processing workshops, etc. all need shoe covers to prevent dust, bacteria, and pollution. When traveling on rainy days, people use shoe covers to prevent water and rain. The present invention relates to a foldable multi-purpose textile shoe cover which is easy to fit and easy to take off, and has a simple and comfortable fit. Summary of the Invention

[0003] The present invention proposes a foldable multi-purpose textile shoe cover, which is made of high-elastic or super-elastic fabric with an elongation greater than 40%, including high-elastic or super-elastic non-woven fabric, and adopts a low-tube shallow-mouth design to maintain a large opening, making it easier and more comfortable to put on and take off. The height ranges from the shallow-mouth shoe cover that only covers the sole to the low-tube shoe cover of 30 cm. The shallow-mouth shoe cover that only covers the sole is mainly used to prevent stains and dust on the sole from dirtying the ground that needs to be kept clean. When the height of the shallow-mouth shoe cover is less than 5 cm, there is a significant gap at the inner bend of the shoe cover because the elastic band of the shoe cover cannot be bent and fit when stretched. If fit is required, a shaping piece is required, such as Figure 9 The shaping piece is in an arc shape close to the inner bend of the shoe, 3-6 cm long and 2-4 cm high, with a double-layer structure. The inner space can fit the elastic band of the shoe cover mouth, and shape the inner bend of the shoe to make it highly fit. The shoe covers are divided into convenient type and shoe-like type, and their performance is divided into functional and decorative. Convenient shoe covers: such as Figure 1, using high elastic or super elastic fabric, made of two pieces of fabric with wavy arcs, it is easy to fold and easy to carry, with elastic band on the cuff, and a straight cuff, suitable for fully automatic production, high efficiency and low cost, the front and back of the shoe cover are arc-shaped, the bottom is wavy arc-shaped, the two ends of the bottom are arc-shaped upwards, and the middle and rear parts are concave upwards, such as Figure 1 2, the concave arc height is 1.5-3.5 cm. This concave arc is a way to solve the problem of fitting the shoe cover with the bends on both sides of the shoe. It can stretch the shoe cover and fit the shoe highly. The back half is 0-4 cm higher than the front half. When the elasticity of the super stretch fabric is large enough, the front and back bottoms can be on the same horizontal plane. When the elasticity is insufficient, the front half is lowered and the back half is raised. Figure 2 , especially the fabrics with high elasticity and super elasticity on both sides, the length of the shoe cover needs to be high elastic, the front cover surface is non-elastic on the horizontal plane, use the front half to press down, the front and back bottom drop is 4-7 cm, change the original circumference of the non-elastic front cover surface, make it into a high-elastic twill, the cover mouth is on the same horizontal plane, the shoes are more fitted, the front and back heights are more coordinated, the length of the shoe cover is 80%-100% of the length of the shoe bottom, the size is adjusted according to the tensile strength of the bottom of the shoe cover, for example: four-sided stretch disposable non-woven shoe cover with an elongation greater than 100%, the bottom generally does not need to be thickened and strengthened, the cover surface and the bottom are at the same level of high elastic tensile strength, while ensuring sufficient tear strength, according to the size of about 80%, can achieve a high fit, easy to put on and take off, In order to achieve a comfortable and beautiful effect, non-disposable shoe covers must be non-slip and wear-resistant, and the process of dipping high-polymer elastic and compliant materials, injection molding, embossing, wrinkling, plastic dripping, and gluing must be used to keep the bottom of the shoe covers soft and elastic, making them easy to put on and take off, easy to fold, and easy to carry. Some fabrics have their own waterproof and breathable functions, but most are not waterproof. To achieve waterproofness for these non-waterproof fabric shoe covers, you can spray a layer of high-elasticity PU film on the fabric, or you can dip a layer of low-modulus, high-elasticity waterproof film inside or outside the shoe covers and perform hydrophobic treatment. When using these processes, the high elasticity and stretchability of the shoe cover surface must be maintained. The shoe covers made with high elasticity and unique structure are easy to carry, easy to clean, highly fit, easy to put on and take off, breathable and comfortable, and beautiful. Shoe-like shoe covers: consist of two parts: the shoe cover bottom and the shoe cover surface, such as Figure 7 , Figure 8The sole of the shoe cover is in the same shape as the sole of the shoe. The shoe cover has no left or right distinction and is symmetrical. The bottom can be made of the same fabric as the top, or it can be made of high-elastic mesh with bone lines, which is dipped in glue to form anti-slip patterns. The mesh can also be completely wrapped around the mesh. The outer periphery of the shoe cover adopts a wavy arc shape, the front half is longer than the back half, and the middle part corresponds to the bends on both sides of the shoe with a concave arc shape. The high-elastic shoe cover surfaces on both sides are disconnected at the front and back, and spliced ​​with horizontal and vertical lines to make their circumference highly elastic. The cuffs are covered with elastic bands. If waterproof shoe covers are needed, you can spray high-elastic PU waterproof film on the cloth, or use a shoe cover mold, dip a layer of waterproof film and do hydrophobic treatment. The bottom needs to be non-slip and wear-resistant. Use polymer elastic and flexible materials for dipping, injection molding, dispensing, dripping, embossing, wrinkling and other adaptation processes to keep the bottom soft and elastic. Shoe-type shoe covers can be made into suitable shoe covers according to different shoes, such as sports shoes, leather shoes, big-toed shoes, high-heeled shoes and other styles. Compared with convenient shoe covers, shoe-type shoe covers are more complicated to make and the cost will be higher. They are not suitable for disposable shoe covers. Convenient shoe covers can be fully automated, such as ultrasonic fully automatic shoe cover machines, which can be formed in one time with high efficiency and low cost. Decorative shoe covers are mainly for decoration. Since no other functions are required, a wide range of fabrics can be selected. As long as the fabrics are highly elastic or super elastic, such as sportswear fabrics, underwear fabrics, knitted fabrics, lace, mesh, etc., the fabrics or cut pieces can be printed, embroidered, offset printed, etc., and can be printed in various styles, such as casual style, sports style, ethnic style, and personalized style. The shoe covers made with high elasticity, especially those ultra-light and ultra-thin fabrics, and in combination with the present technical structure, can fit tightly with the shoes and show the beautiful shoe shape, just like athletes wearing tight sportswear or beautiful women wearing tights. The visual beauty exceeds the shoes themselves. The decorative shoe covers have a broad market. The present invention has a simple structure, is easy to produce, and has low cost.

Figure 2 This is a diagram of the structure of a convenient shoe cover with high elasticity on both sides. Figure 3 This is a diagram showing the fitting effect of a convenient shoe cover embodiment when it is put on a shoe that is higher than 10 cm. Figure 4 This is a picture of the fitting effect of the convenient shoe cover with a height of 6 cm to 8 cm on the shoes. Figure 5 This is a shoe-shaped shoe cover with a height of 6 cm to 8 cm and a colorful flower shape. Figure 6 This is the effect picture of putting shoes on the bottom of the shoe-shaped shoe cover. Figure 7 This is a diagram of the sole structure of a shoe-like overshoe. Figure 8 This is a structural diagram of a single piece of shoe cover. Figure 9 It is a double-layer structure shaping piece used when low-sized shoe covers have large gaps due to side bends. Example: Foldable multi-purpose textile shoe covers, convenient shoe covers, 1. Cut the four-sided high-elastic fabric into two identical wavy arc-shaped pieces, such as Figure 1, use overlock sewing machines, four-needle six-thread, hot melt glue machines, ultrasonic and other equipment for splicing, overlock rubber bands for shoe covers, disposable shoe covers do not need to be overlocked with rubber bands, because they are made of high-elastic fabrics, elastic wrapping, and the bottom can be made non-slip and wear-resistant as needed. Use polymer elastic and flexible materials for dipping, injection molding, glue dripping, dispensing, embossing, wrinkling, etc., a variety of process options to ensure that the bottom is soft and elastic, making it easy to put on and take off, easy to fold, and easy to carry. If you want waterproofing, you can spray a layer of high-elastic PU film coating on the fabric, or you can use shoe covers, dip a layer of low modulus, high-elastic waterproof membrane into the mold and do hydrophobic treatment, 2. The high-elastic fabric on both sides needs to be changed Change the cloth texture, press down the front half and raise the back half, with a front-to-back drop of 4-7 cm at the bottom. The non-elastic texture of the front shoe cover surface is changed into a high-elastic twill. The production method is the same as the four-sided stretch shoe cover process. 3. Use a fully automatic ultrasonic shoe cover machine to make it. Place the whole roll of high-elastic fabric cut to size on the feed reel of the shoe cover machine, and place elastic bands on both sides. The shoe cover machine will sew the elastic bands on both sides of the cloth, and then fold it in half and overlap it. When the elastic band is stretched to make the cloth flat, weld and cut the shoe cover except for the elastic bands at both ends, and then weld and cut the elastic band parts at both ends. The non-woven disposable shoe cover is ready. Non-disposable shoe covers should also be waterproof, non-slip and wear-resistant as needed. Figure 3 , Figure 4 , is a simple rendering of a highly fitting effect.

[0005] Example: Foldable multi-purpose textile shoe covers, shoe-shaped shoe covers, such as Figure 5 , Figure 6 , use four-sided high elastic fabric, cut out the shoe cover surface and shoe cover bottom according to the proportion size of 75%-90% of the shoe size, the shoe cover bottom is the same as the sole, such as Figure 7 The bottom and the surface can be made of the same fabric, or high-elastic mesh can be used as the bottom, or other high-elastic materials can be used as the bottom, and the surface can be made of a single piece of splicing, such as Figure 8 , the splicing is placed on the heel of the shoe cover, or two or more pieces can be spliced ​​together, the joints of the two pieces are placed at the bends on both sides, the cover is sewed with elastic, or raw edges, such as Figure 3 The shoe cover opening is spliced ​​with an overlock sewing machine, four-needle six-thread, hot melt glue machine, ultrasonic and other machines. The waterproof fabric is coated, or a low-modulus, high-elasticity waterproof membrane is dipped with a shoe cover mold and hydrophobic treatment is performed. The bottom is made of a polymer elastic and compliant material mold and dipped with glue, injection molding, embossing, wrinkling, glue dripping, and dispensing to keep the bottom soft and elastic, making it easy to put on and take off, easy to fold, and convenient to carry. The two sides of the high-elastic fabric are spliced ​​at the bends on both sides, and the horizontal lines are spliced ​​with the straight lines. The rest is the same as the four-way stretch production.
